We have sureveyed about 30,000M of Sarna. It is a bit reflective so make sure its cold and dark when you survey, always get 2-3 angles of every defect to help eliminate anomalies caused by reflections. We always walk the perimeter of the roof taking images every 10m. Walk clockwise, take diagionals at the end and make sure you match up the visual images with the right thermographs - acres of Sarna look very similar back in the office!
